I have a 2011 grand sport with the paddle shift automatic, and am looking at aftermarket exhaust systems. Not looking for a loud system, but something that will sound good without increasing interior noise levels very much. Is there a system that would for me... and would an aftermarket system negate the factory warranty?

BWM C6GS

Have a look at the new design Borla S-Type II, or maybe the Touring more to your liking. Corsa Sport also very popular and not too agressive. Both with little or no-drone. Check out sponsoring vendor(s) for details and links or go Borla website for cool descriptive video with Grand Sport installed systems on Bondurant Cars. Also YouTube. The GS has an OEM X-pipe. No way a cat- or axle back would affect warranty. Their just a muffler set. Lots of choices and opinions. Good luck hunting.

Do you have NPP? If not this is a good option, quiet when you want and louder when you want.

Corsa Sports are a very nice option with the A6

I installed the Flowmaster Force II axle-back system on my 2012 A6 Coupe. I really enjoy the sound, and IMO it's hard to beat for the price. There's resonance or "drone" from 1400 to 2100 RPM, but nothing I can't live with. I'll get a video/audio capture this evening and try and post it to give you at least some idea what it sounds like, but it has a very deep quality and isn't loud enough to bother friends/neighbors.

While I have the NPP option on my '12, I have always loved the Flowmaster sound.

NPP is a great option.

My Denali Diesel sounds better than NPP! B&B or Corsa.

Thanks for all the info! Found the sound I was looking for.

What did you decide to go with?

ghorner

Leaning towards the corsa. Any advice about changing the intake filter?

i hate to be negative on boards but that flowmaster exhaust looks like ***. it looks crappier than the stock non-npp exhaust for god sakes.

Go with the Corsa Sport. I have it on my 09 and I love it. I didn't change my intake filter, I left the car as it was. It's plenty loud with the Corsa.

Other than sound, Is their any benefit or improved performance? I have '08 with Halltech Super bee CAI and Kooks 1 7/8" into 3" catted x pipe and a good Tune into stock non NPP cans..RWHP 397..will Corsa/B&B/ Borla really improve that?

peter pan

Your mufflers are restrictive, go with the above mentioned or NPP and you will pick up a few with a better sound

Ritchie, how's the interior noise level while cruising?

Man I love Callaway, but that exhaust.......

Go with the Corsa Sports. Not too loud, but nice sounding. No drone.
